BROOKINGS, S.D., Aug. 14 /PRNewswire-FirstCall/ — VeraSun Energy Corp. , one of the nation’s largest ethanol producers, today announced the startup of its 110 million gallon per year ethanol biorefinery located near Hartley, Iowa. The Hartley production facility marks the 13th VeraSun biorefinery in operation, increasing the company’s annual production capacity to more than 1.3 billion gallons.

“We are pleased to bring our Hartley ethanol biorefinery into production,” VeraSun CEO Don Endres said. “It is one of the largest and most efficient facilities in the nation and further expands VeraSun’s production platform to provide additional scale to our business. We appreciate the support of our team, business partners, and the community of Hartley to help make this day a reality.”

Located on a 350-acre site west of Hartley, construction on the facility began in November 2006. The biorefinery will annually process approximately 39 million bushels of corn and produce about 350,000 tons of distillers grains for livestock feed, in addition to employing approximately 55 workers.

VeraSun Hartley is the fourth VeraSun facility to come on-line this year, joining sister production facilities in Marion, S.D., Bloomingburg, Ohio, and Hankinson, N.D. According to the Iowa Renewable Fuels Association, the Hartley facility is the 31st operating ethanol biorefinery in the state of Iowa, expanding overall production throughout the state to almost 2.5 billion gallons annually.

“At 2.5 billion gallons, Iowa is producing more ethanol than what that state consumes in gasoline annually, thus becoming a net exporter of transportation fuel,” Endres said. “While the national debate continues on how to solve our energy crisis, Iowa is showing the nation how we can become less reliant on foreign oil today.”
